This study aims to explore consumers’ preferences on different types of shampoo products among women aged 20s and 30s from Beijing and Shanghai. 100 women who have scalp troubles were selected as respondents. By conducting HUT blind test, we compared the consumers’ feedbacks on 3 scalp care shampoo products but with 3 different formulations, i.e., 2 products with silicone-free formula and 1 product containing silicone oil. We adopted quantitative methodology through the whole analysis, and evaluation results of different groups were obtained by PCA analysis. The results of the study are recapped as follows: (1) Although there is no obvious difference in consumers’ preference among different ages, there are obvious differences in different regions. (2) Beijing consumers are satisfied with the sensory efficacy of the 3 products while Shanghai consumers are less satisfied with any of them. It is speculated that Shanghai consumers have a higher expectation for scalp care products; (3) Products containing silicone oil shows higher usage satisfaction when compared with silicone- free formula. It is better to emphasize long-term efficacy for silicone-free formula when planning GTM strategy, so that it could guide consumers to achieve their post-purchase rationalization. (4) Although the tested products all have scalp care function, consumers are more concerned about the effects on the health status of the hair than the scalp care effects.

This review surveys relevant and recent data of the pertinent literature regarding the acute effect of alcohol on various kinds of memory processes with special emphasis on working memory. The characteristics of different types of long-term memory (LTM) and short-term memory (STM) processes are summarized with an attempt to relate these to various structures in the brain. LTM is typically impaired by chronic alcohol intake but according to some data a single dose of ethanol may have long lasting effects if administered at a critically important age. The most commonly seen deleterious acute effect of alcohol to STM appears following large doses of ethanol in conditions of “binge drinking” causing the “blackout” phenomenon. However, with the application of various techniques and well-structured behavioral paradigms it is possible to detect, albeit occasionally, subtle changes of cognitive processes even as a result of a low dose of alcohol. These data may be important for the consideration of legal consequences of low-dose ethanol intake in conditions such as driving, etc.

ABSTRACTImplants are essential for the repair of retinal detachments. The implant buckles the wall of the eye and apposes the detached retina with the choroid, thus restoring light sensitivity to the retina. The scleral buckling also relieves traction on the retina from a shrinking vitreous body. The implant materials most commonly used are solid silicone rubber and silicone sponges, but both types have some disadvantages. A poly(hydroxyethyl acrylate-co-methyl acrylate) hydrogel implant with improved properties of softness and antibiotic absorption is also available for retinal detachment surgery. Proliferative vitreoretinopathy involves various conditions of retinal detachment complicated by vitreous fibrosis, which, after vitrectomy, may be treated with intraocular injection of fluids that support the retina against the choroid. For conditions requiring a long-term implant, silicone oil although controversial is the material of choice. Many other substances have been investigated but none better has yet been found.

Types Of Information

Visual long-term memory has a large and detailed storage capacity for individual scenes, objects, and actions. However, memory for combinations of actions and scenes is poorer, suggesting difficulty in binding this information together. Sleep can enhance declarative memory of information, but whether sleep can also boost memory for binding information and whether the effect is general across different types of information is not yet known. Experiments 1 to 3 tested effects of sleep on binding actions and scenes, and Experiments 4 and 5 tested binding of objects and scenes. Participants viewed composites and were tested 12-hours later after a delay consisting of sleep (9pm-9am) or wake (9am-9pm), on an alternative forced choice recognition task. For action-scene composites, memory was relatively poor with no significant effect of sleep. For object-scene composites sleep did improve memory. Sleep can promote binding in memory, depending on the type of information to be combined.

Carbon quantum dots (CQDs) are emerging novel nanomaterials with a wide range of applications and high biocompatibility. However, there is a lack of in-depth research on whether CQDs can cause acute or long-term adverse reactions in aquatic organisms. In this study, two different types of CQDs prepared by ammonia citrate and spermidine, namely CQDAC and CQDSpd, were used to evaluate their biocompatibilities. In the fish embryo acute toxicity test (FET), the LD50 of CQDAC and CQDSpd was about 500 and 100 ppm. During the stage of eleutheroembryo, the LD50 decreased to 340 and 55 ppm, respectively. However, both CQDs were quickly eliminated from embryo and eleutheroembryo, indicating a lack of bioaccumulation. Long-term accumulation of CQDs was also performed in this study, and adult zebrafish showed no adverse effects in 12 weeks. In addition, there was no difference in the hatchability and deformity rates of offspring produced by adult zebrafish, regardless of whether they were fed CQDs or not. The results showed that both CQDAC and CQDSpd have low toxicity and bioaccumulation to zebrafish. Moreover, the toxicity assay developed in this study provides a comprehensive platform to assess the impacts of CQDs on aquatic organisms in the future.

These days there are undeniably unique materials that, however, must also meet demanding safety requirements. In the case of vehicles, these are undoubtedly excellent fire protection characteristics. The aim of the work is to experimentally verify the proposed material compositions for long-term heat loads and the effect of thickness, the number of laminating layers (prepregs) as well as structures with different types of cores (primarily honeycomb made of Nomex paper type T722 of different densities, aluminum honeycomb and PET foam) and composite coating based on a glass-reinforced phenolic matrix. The selected materials are suitable candidates for intelligent sandwich structures, usable especially for interior cladding applications in the industry for the production of means of public transport (e.g., train units, trams, buses, hybrid vehicles).

Abstract Background In order to provide efficient public health decisions making, it is crucial to obtain reliable and recent data on the state of health of the population. For that purpose, a web-platform for the dynamic monitoring of the health status and well-being of the population is being developed in the Geneva canton. Methods Using a dedicated website, recruitment will be carried out over 5 years so as to enroll up to 20 000 volunteers, resident in Geneva and aged ≥ 18 years, followed-up for at least 10 years. Once connected to the website, participants will fill a general self-administered questionnaire on their socio-demographic and lifestyle characteristics, anthropometry, health status, physical activity and diet. Environmental, behavioral and occupational exposures will also be evaluated via more specific questionnaires. Current addresses of residence will be geocoded and linked to geographical databases to passively gather information on noise, air pollution, green areas, and other exposures. Surveillance of health events will be implemented via yearly self-administered on line questionnaires and potentially via passive linkage to medical databases (medical file) and health registries with the participants' consent. For a subsample of volunteers, biochemical samples and biomarkers will be collected. Results The pilot study shows that the project is feasible, potentially cost-effective but requires innovative methodologies for ensuring long term follow-up. Different communication strategies used for recruitment and long-term participation need to be implemented ensuring trust from participants, different levels of health literacy and the need of justice. Conclusions Specchio is a new project aimed at setting up a digital longitudinal health study in Geneva. Challenges concerns the determinants of participation, recruitment and attrition, quality of data and ethics. Long-term funding by the Directorate General of Health Geneva is currently under evaluation. Key messages This digital longitudinal health study will enable dynamic monitoring of the health status and well-being of Geneva residents and will enable efficient public health decision making. Specchio is a new project funded by the Directorate General of Health Geneva.

Corporate Social

With the rapid development of the economy, corporate social responsibility (CSR) is receiving increasing attention from companies themselves, but also increasing attention from society as a whole. How to reasonably evaluate the performance of CSR is a current research hotspot. Existing corporate-social-responsibility evaluation methods mostly focus on the static evaluation of enterprises in the industry, and do not take the time factor into account, which cannot reflect the performance of long-term CSR. On this basis, this article proposes a time-based entropy method that can evaluate long-term changes in CSR. Studies have shown that the completion of CSR in a static state does not necessarily reflect the dynamic and increasing trend of CSR in the long term. Therefore, the assessment of CSR should consider both the static and dynamic aspects of a company. In addition, the research provides the focus of different types of forestry enterprises in fulfilling CSR in the long term, and provides a clearer information path for the standard identification and normative constraints of different types of forestry enterprises CSR.
